Abstract: ABSTRACT OF THE DISCLOSURE    An injection Molding machine includes a stationary mold half and a movable mold half.  The stationary and movable mold halves cooperatively define a mold cavity for injection molding an end closure article having a base and a recloseable tab molded in an open position relative to the base.  A thermoplasti material is injected into the mold cavity to form the end closur article.  The movable mold half is then separated from the stationary mold half to open the mold cavity, and the tab of the end closure article is closed prior to ejecting the end closure article from the open mold cavity.

Abstract: ABSTRACT      This invention relates to a new and novel method and apparatus for reacting nongaseous material with a gaseous reactant comprising introducing a first stream containing a nongaseous material into a reaction zone; simultaneously introducing a second stream containing a gaseous reactant into the reaction zone such that the gaseous reactant immediately contacts and reacts with the first stream thereby producing a gaseous product; forming a spiralling vortex within the reaction zone to cause substantial separation of gases, including the gaseous product, from the nongaseous material; forming and removing a third stream from the reaction zone containing the gaseous product which is substantially free of the nongaseous material before a major portion of the gaseous product can react with the nongaseous material; and forming and removing a fourth stream containing the nongaseous material from the reaction zone.    The method may be performed in an apparatus comprising a reactor structure having a covered cylindrical chamber; a conical portion attached to the chamber opposite the covered end thereof; an inlet for directing a first stream containing a nongaseous material tangentially into the chamber such that nongaseous material forms a spiralling vortex which is urged towards the conical portion; a means for simultaneously introducing a second stream containing a gaseous reactant into the chamber such that the gaseous reactant immediately contacts the first stream; a first outlet located in the covered end of the chamber, and oriented along the axis thereof for removing gases; and a second outlet located at the smaller diameter end of the conical portion for removing nongaseous material.

Title: Continuously variable controlled ratio gear transmission

Granted: 1980-01-01
Abstract: ABSTRACT     A power transmission system for small vehicles or machinery having a principal forward speed and variable forward and reverse speeds capable of providing lower variable speeds is disclosed.  The transmission system includes a primary transmission and a secondary transmission connected in series.          In one of three positions, the two transmission housings and primary output shaft are keyed together.  This results in a non-variable output, principal forward speed with a 1 to 1 ratio between the speed at which the engine rotates the primary transmission housing and the speed of the output shaft.  In a second setting, the secondary transmission hous-ing is keyed only to the output shaft from the primary trans-mission.  This results in a forward speed having a variable output depending upon the load placed on the input shaft to the primary transmission.  In a third position, the housings for the primary and secondary transmissions and the output shaft from the primary transmission are each disengaged from each other.  In this setting, the secondary transmission functions to reverse the direction of the output shaft while the primary transmission functions to provide a variable gear ratio depending upon the load placed upon the input shaft to the primary transmission.

Abstract: Abstract of the Disclosure A photocopy resistant article, useful, for example, in the preparation of share certificates, bond certificates, paper money, etc. is disclosed.  Two adjacent areas of the surface of the photocopy resistant article appear visually continuous to the unaided normal human eye.  However, one of the areas, known as the signalling area, comprises a plurality of spaced lines having an element frequency along a notional selected line which is within the resolution capability of the photocopy machine but substantially beyond the resolution capability of the normal unaided human eye.  The second of the two adjacent areas, referred to as the comparison area, comprises a plurality of spaced lines having an element frequency along a selected notional line substantially beyond the resolution capability of the unaided normal human eye and of the photocopy machine.  Both areas have approximately equal area occupancy ratios and the signalling area has a density above the sensitivity threshold of the photocopy machine.

Abstract: TRUSS JOISTS     Abstract of the Disclosure A truss joist includes an upper chord, a lower chord and a series of links.  The series of links connects the upper and lower chord and terminates in an end link which is attached to the lower chord and extends upwardly toward the terminal portion of the upper chord.  An end bracket which partially surrounds the terminal portion of the upper chord includes a U-shaped channel which contacts the side and bottom surface of the upper chord.  The U-shaped channel further comprises a pair of downwardly projecting legs for connectively receiving the flattened end portion of the end link.  One embodiment of the end bracket lies directly upon the upper surface of a support member.        Another embodiment is flush-mounted against the inner surface of the support member and has a horizontal flange which extends over the upper surface of the support member.  Additional embodi-ments of the end bracket include adjustable bracket elements mounted below the U-shaped channel and on either side of the downwardly projecting legs.  Since those adjustable end brackets are slidably connected to the end bracket, they allow the length of the truss joist to be adjusted.  These adjustable bracket elements include flat end surfaces which permit them to be nailed to the inner surface of the support member and thereby assist in securing the end bracket to the support member.

Abstract: ABSTRACT OF THE DISCLOSURE      A continuous wave, phase measurement system which provides at least an order of magnitude improvement in accuracy over modulated carrier systems is disclosed for the determination of the thicknesses of layered targets consisting of a known number of dielectric layers, each of a known maximum thickness.  This system uses related frequencies such as the fundamental and its harmonics to establish a multi-harmonic coherence relationship whereby a homodyne phase reference between harmonics can be conserved and information extracted from just the received and not the transmitted signals. Consequently doppler effects due to motion between the target and the apparatus, as well as severe local oscillator stability and drift limitations are avoided, and thus this system can measure remote target parameters by interferometric techniques without the distance being a constraint.

The shroud exit encloses the fan and in-cludes throat (CF) radial expander (R) and radial flat (RF) sections whereby air is drawn through the heat exchanger axially and expelled radially along said exit sections.  The fan has a projected axial width (AW) such that a general relationship exists with the shroud exit sections: CF = AW/3, RF = AW/3, and R = 2AW/3.  A barrier located behind the fan and away from the heat exchanger eliminates air recirculation in the fan hub region.

Abstract: ABSTRACT              An improved liner assembly for an ore grinding mill is disclosed, which comprises a plurality of liner segments that are individually mounted to the shell of the mill.  Each of the segments bodies defines a mounting surface that engages the shell surface, and a grinding surface that faces inward for comminuting the ore.   The sides of each segment are configured so that the cross sectional dimension of the segment decreases toward the mounting surface, thus defining pockets between the segments.  Theses tapered pockets avoid the problem of segment removal which results from peening of the segments, and the wedged entry of fragmented material which tends to from an integral structure.  Preferably, longitudinal, wedge-shaped inserts are placed and loosely retained in the tapered pockets to protect the mounting surface and prevent the trapped entry of fragmented material.
